To find the eigenvalues in the half-open interval $ \left(\vphantom{-2, 2}\right.$ -2, 2$ \left.\vphantom{-2, 2}\right]$, and the corresponding eigenvectors, of the Hermitian band matrix

A = $\displaystyle \left(\vphantom{
\begin{array}{ccccc}
1 & 2 - i & 3 - i & 0 & 0...
...i & 4 + 3i & 4 & 5 - 4i \\
0 & 0 & 5 + 3i & 5 + 4i & 5
\end{array} }\right.$$\displaystyle \begin{array}{ccccc}
1 & 2 - i & 3 - i & 0 & 0 \\
2 + i & 2 &...
...0 & 4 + 2i & 4 + 3i & 4 & 5 - 4i \\
0 & 0 & 5 + 3i & 5 + 4i & 5
\end{array}$$\displaystyle \left.\vphantom{
\begin{array}{ccccc}
1 & 2 - i & 3 - i & 0 & 0...
...i & 4 + 3i & 4 & 5 - 4i \\
0 & 0 & 5 + 3i & 5 + 4i & 5
\end{array} }\right)$.
